US Patent 10585051 X-ray computed tomography gauge

A method of making a gauge for verifying or calibrating an x-ray computed tomography device positions a first plurality of objects on a first substrate, and a second plurality of objects on a second substrate. The method also certifies the positions of both the first plurality of objects on the first substrate, and the second plurality of objects on the second substrate. After certifying both the first and second plurality of objects, the method couples the first substrate with the second substrate.
